Check Digit Verification of cas no
The CAS Registry Mumber 49602-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,0 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49602-75:
(7*4)+(6*9)+(5*6)+(4*0)+(3*2)+(2*7)+(1*5)=137
137 % 10 = 7
So 49602-75-7 is a valid CAS Registry Number.

New Synthesis of Isoxazoles and Isothiazoles. A Convenient Synthesis of Thioenaminones from Enaminones
Lin, Yang-i,Lang, Stanley, A.
, p. 4857 - 4860 (2007/10/02)
The reaction of 1-aryl-3-(dimethylamino)-2-propene-1-ones (enaminones) and 1-aryl-3-(dimethylamino)-2-propene-1-thiones (thioenaminones) with hydroxylamine-O-sulfonic acid gave, respectively, isoxazoles in 76-84 percent yields and isothiazoles in 60-65 pe
